Back in January Microsoft encrypted all my hard drives without saying anything. I was playing around with a dual boot yesterday and somehow aggravated Secureboot. So my C: panicked and required a 40 character key to unlock.
Your key is backed up to the Microsoft account associated with your install. Which is considerate to the hackers. (and saved me from a re-install) But if you've got an unactivated copy, local account, or don't know your M$ account credentials, your boned.
Control Panel > System Security > Bitlocker Encryption.
BTW, I was aware that M$ was doing this and even made fun of the effected users. Karma.
If you only used TPM for bitlocker with no pre-boot authentication or something similar, it's possible that you had the "MaxDevicePasswordFailedAttempts" policy configured. Apparently that is configured by default if you use the security baseline.
IMO it makes a lot of sense to lockdown and require bitlocker recovery if there has been a few failed attempts.
We use bitlocker on probably over 1000 devices I don't believe we had any substantial issues with it. Of course users occasionally get locked out, but that should be planned for and a process should be in place to help them.
I suggest deploying windows hello or smart cards to reduce the dependency on passwords. Window hello for business is especially great since it's free, secure and way easier and faster for users to use, especially if your devices have fingerprint readers or face recognition. I wish Linux and MacOS had anything as useful as Windows Hello.
Yeah I'm with you. I also manage about 800 devices at my current role and I've never had any major issues with BitLocker.
I'm tempted to think they're just lying but that's a little mean. Maybe they just didn't know? I don't know but BitLocker is not the problem here.
